F'INGER-HQLD FOR PENHOLDERS.

Tn Il :ft/mr if muy concern.-

Be it known that l, Bvro.\v B. (lotus-inrit, g a citizen of thev UnitedStates. residing 1n the .soft-rubber sleeve could have nogreat tliiclttcity and State ot' `t\`e.v 5orlt, have invented a new and usefullinproveincnt in Finger-Holds for lenholders, ot' which the following isa i sleeve by means ot tiny air-cells distributed invention is toprovide a specitication.

The object of my linger-hold for pe'nholdeis which shall be Q easy ofconstruction and which '.vill vet present an elastic and yielding' massto the lingertips of the writer, so that the pcnholder may i be securelygrasped with little eliort, an increased degree of elasticity andsmoothness be i given to t'nc writing, and writers cramp be. avoided.

ltlias heretofore heen proposed with a view l oi' attainingr the objectsat which I aim to construct linger-holds for penholders of coi-lt;

but these have been found unsatisfactory by solid sot'tl rubber, sincein my form the walls' reason of their comparatively unyicldin; r`

chanac-ter. ,It has also been proposed to build the linger-hold ot'sot'trubher. Now a lingerhold of a solid cylinder of soft rubber withoutany core of rigid material on the inside is impmcticable, since itwabblcs in writinfr.

lt has therefore been proposed to build penholders with a solid coie'orferrule, which supports and prevents the wabbling,r of the pen. and tosurround this core or foi-rule with :lsoft-rubber sleeve inthe forni Gt'a tube. Since. however, the body ot the surrounding advantage that thclingers ofthe user displace the air from the 'very point at which thelingers rest. thus practically permitting. the lingers to come intoContact with the rigid material of the penholder with nothing but a thin'sheath of rubber between them.

Xoivl have found that l'can. construct a linger-hold com prisng asleeve'of soft rubber having a comparatively thin body and incaspart wayoi' entirely through the body of the linger-hold. A linger-hold thusconstructed has far greater elasticity than one built of of sottruhherbetween the air-cells are comparatively thin and can be bentandstretched with the application of the minimum force, and this remains.too, in a measure even after the rubber has grown somewhatstili withage.

In the drawings, Figure 1 shows a crosssection of a penholder and mylinger-hold. Fig. 2 shows a longitudinal cross-section of a modiliedform of linger-hold. Fig. 3 is aseotion ot` Fig. .2 along the'line 3 3.Fig. 4 is a longitudinal section of another modilied form ot'linger-hold. Fig. 5 a 'section of Fig. 4 along the line 5 5.

\\'hile my linger-hold may be applied to penholders of variousconstructions, I have shown,- to lix ideas, a holder in the form of a.stem A, having a tenori A', over which is slipped the metal core orferrule B, having fastened in the outer end thereof the usualpenholder-elip ll'. The multicellular soft-rubber sleeve l) is shown assurrounding and embracing the metal core or terrule B. Manifest-ly,however. the material of the sleeve could be extended to cover theentire penholder.

The sleeve D in Fig. 1 is constructed of soft 4rubber having a verylarge number of tiny ot` these little air-cells is preferably lessthar uthe linger-hold.

one-ftieth ofl an inch'. the radial thickness'of the c 'vlindriv thesleeve is not over an eighth er in extreme 1 somewhat regularlydistributed,k and their number is in practice even larger than I haveindicated. y

1n the formof sleeve shown in -i the air-cells are again prismatierather than polyhedral in form; but instead of running longitudinallyalong the sleeve they eireumferentially aroundV it at the same and abdif'- fering radial distances from the axis of the sleeve.

ll'hile I have referred to the materiell of the sleeve as "soft rubber."it is to be understood that I include by thisterm not merely pu re softrubber, lbut also that form of soft rnbb which pure softrnbber is mixedwith terating or other efiunpounds Vfor the sa greater eheapness or forimparting eth1 sirable characterisaies to the soft rubber 1. A penholderlinger-hold compris rigid core for holding the pen and a surr ingsoft-rubber slee're havingvair-eell tributed throughou its mass,substanti: described.

Q. A penholder Enger-hold compris rigid tubular pen-noldng ferrule androunding soft-rubber sleeve having ai distributed throughout its mass,substtu as described.

In testimony whereof I have signed m5 to this specification in thepresence of tu scribing witnesses. v
